Programming

my project is very big,has many module and sub procedure that
written by others,so how to get info of thel file opened or unclosed in my project ?
I think there are two ways:
1. with pid_t get process info ,and via file table ( /usr/include/sys/file.h) to check file info.
2. in very beginning of project ,catch all detail of file table,
and recheck it in the end of project ,so I can tell how many
file were opened and how many were not closed .


but I do not know how to do it !!!
Could you help me!!! Thanks!!!

It seems to me that this would be something you would ask the head of your project (read teacher). See rule six

Thanks for reply!
but I got there for helping not for how to work or live.
if your do know ,please tell me answer .
if your do not know ,do not say " go to ask your teacher ..
go to ask your manager..."etc, please!!!!

it's not a situation of rule 6, and if you insist,everyone,every question is the same situation,cause we alway got problem in
studying or working ;
